Re: Xperia z5 Premium battery Drain so fast

Yup battery drain is very fast, on my Z2 I'd wake up to around 86% battery. My Z5 Premium 50% something is definitely wrong. I'm not factory resetting my phone and going through all that trouble of downloading all my apps again. This needs to be fixed!

The phone also is sluggish and it's actually crashed on me once! So much for an 8core processor!

Re: Xperia z5 Premium battery Drain so fast

Same issue as khizar, the z3 had an amazing battery life but the Xperia z5 premium drains so fast. I was at 100% and checked on power management the estimated battery time. In stamina mode 12 hours, when I took the stamina out 4hours!!!! The phone is amazing with the stereo speakers, water resistance, screen, finger scanner, additional memory, dual sim and fast charging but the lack of proper power management is a serious drawback. I've had every z series for the exception of the z3+. The z3 was the best model when you think that the phone easily could go for 20 hours on heavy duty. I've had pretty much every single premium phone on the market operating on android. My prior phone was the LG G4 but the motherboard crashed and is now for repair. So I went for the Xperia being always really happy with the z series. Unless Sony comes up with a proper update for improving the battery in a very very near future, I will return to my qhd LG G4 with the additional battery.

I do not use Stamina mode, and I get at least 14 hours. All my other Z devices get the same with the exact same setup in terms of apps. If I turned on Stamina mode I'd probably may be able to go 2 days before charging which I have yet to try out.

Re: Xperia z5 Premium battery Drain so fast

Hi khizar, I just did a factory reset and it seems to be the miracle solution. I don't know why it changed my battery consumption, but I did a backup through the Gmail account, factory reset and restored all data and re-uploaded all the previous apps. The battery works like a charm. Keep you updated to see if it remains stable.
